squid: denial of service

Package(s):squid CVE #(s):CVE-2011-4096
Created:November 18, 2011 Updated:January 6, 2012
Description: From the Red Hat bugzilla:

An invalid free flaw was found in the way Squid proxy caching server processed DNS requests, where one CNAME record pointed to another CNAME record pointing to an empty A-record. A remote attacker could issue a specially-crafted DNS request, leading to denial of service (squid daemon abort).
